Voltage Multipliers
In voltage multiplier circuit two or more peak rectifiers are cascaded to produce a d.c voltage equal to multiplier of the peak input voltages

Magnetic Amplifier
The diagram of magnetic amp or magnetic amplifier is shown in figure below, only silicon diodes are added in series with each winding of the saturated reactor.
Direct Coupled Amplifier
As shown in the below diagram, the direct coupled amplifier (DC) is consist of two transistors Q1 and Q2 , a voltage divider
Class C amplifier operation
A class C amplifier is biased so that it conducts for less than 180° of the input. It will typically have a conduction angle of 90° to 150°.
Chopper Amplifier
Let us assume that we are required to amplify a small signal say of the order of millivolt and that the signal v(t) is one in which change in volt with respect to time i.e.
